[0002] The scraper is a thin sheet used to scrape off excess ink on the surface of the roller on the printing press. With the advancement of science and technology, the trapezoidal scraper is increasingly being used by printing companies because its contact area with the plate roller is constant from beginning to end, and the printing quality is consistent. The scraper needs to be taken down for inspection after scraping ink for a period of time, mainly to inspect the flatness and scratches of the scraper. The flatness of the scraper is very important for scraping ink, because if the scraper is not flat, it will cause an uneven ink layer and affect the printing quality. Therefore, it is very important to regularly inspect the flatness of the scraper.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] Real-time monitoring equipment for ink scraper used in the preparation of tipping paper, as shown in the attached figure of the specification Figure 1-Figure 14 As shown, it includes a detection device 1, and a detection instrument 11 is set in the detection device 1 to detect and analyze the scraper; the detection device 1 includes:

[0041] A rotating drum 12 is rotatably connected to the inside of the detection device 1. The rotating drum 12 is connected to a motor 13 provided in the detection device 1. A correction plate 14 is provided on the rotating drum 12. The detection device 1 is located above the rotating drum 12 and is slidably connected to a tool holder 15, in which a scraper is installed. The tool holder 15 is connected to an electric telescopic rod 16 provided on the inner wall of the detection device 1. The blade of the scraper contacts the correction plate 14. A lamp 17 and an imaging assembly 18 are provided on the inner wall of the detection device 1. The lamp 17 and the imaging assembly 18 are symmetrically distributed with the contact part of the correction plate 14 and the scraper as a reference. The light source of the lamp 17 passes through the gap between the contact part of the correction plate 14 and the scraper, and forms a pattern on the imaging assembly 18 according to the principle of pinhole imaging. The imaging assembly 18 is a conventional device for pinhole imaging. The imaging assembly 18 detects the flatness of the blade of the scraper according to the size of the pattern.

[0042] A cleaning tank 2 is provided on the rotating drum 12, and a sealing door 21 is slidably connected in the cleaning tank 2 through a spring, and the sealing door 21 is symmetrically distributed; a support rod 22 is evenly hinged on the top of the sealing door 21 through a torsion spring, and the ends of adjacent support rods 22 are hinged to each other, and the support rods 22 are inclined; a pressing block 23 is provided at both ends of the bottom of the tool holder 15 near the scraper, and the pressing block 23 contacts the support rod 22; a storage tank 24 containing a cleaning solution is provided in the detection device 1, and the storage tank 24 is connected to the cleaning tank 2 through a water pipe; a circulating air pump 25 is provided on the detection device 1, and the circulating air pump 25 is divided into The air outlet 26 and the air suction port 27 are respectively connected to the inner walls on both sides of the detection device 1; the support rod 22 is hinged at the position where the sealing doors 21 are close to each other, and the ends of the two support rods 22 close to each other on the two sealing doors 21 are hinged to each other, and the hinge position of the two support rods 22 is located above the contact position of the two sealing doors 21; the circulating air pump 25 is used to circulate the air in the detection device 1 and blow the ink scraper to accelerate drying; the storage tank 24 is a conventional tank device for storage and suction and transportation, so that the storage tank 24 can not only store the cleaning solution, but also transport and suction the cleaning solution;

[0043] Specific work flow: when the ink scraper is monitored in real time, the ink scraper is removed and installed in the knife holder 15, and then the detection device 1 controls the motor 13 to drive the rotating drum 12 to rotate, and the rotating drum 12 drives the cleaning tank 2 closed by the sealing door 21 to rotate to the bottom of the ink scraper; then, the electric telescopic rod 16 drives the ink scraper to approach the cleaning tank 2 through the knife holder 15, and the knife holder 15 squeezes the hinged part of the two support rods 22 from top to bottom through the pressing block 23, and squeezes the support rods 22 downward. After the two support rods 22 are squeezed, the inclined state changes to the horizontal state, and the sealing door 21 is pushed into the rotating drum 12, so that the cleaning tank 2 is opened when it rotates to the horizontal upward state; when the pressing block 23 does not squeeze the support rod 22, the cleaning tank 2 is in an inclined state, and the sealing door 21 closes it to prevent the internal cleaning solution from dripping or being thrown onto the instrument due to rotation, affecting the detection work;

[0044] After the cleaning tank 2 is opened, the storage tank 24 injects the cleaning solution into the cleaning tank 2 through the water pipe, and the circulating air pump 25 starts to circulate and remove dust from the air in the detection device 1 to prevent impurities from floating or adhering to the surface of the scraper after cleaning, thereby affecting the detection work; the electric telescopic rod 16 drives the scraper to soak for a specified time through the knife holder 15, and then drives the scraper to rise and fall in the cleaning solution at a fixed lifting speed and amplitude, thereby achieving a contactless washing effect, accelerating the cleaning efficiency of the scraper and improving the cleaning effect, so as to prevent the agglomerated ink from being difficult to clean and affecting the detection work, thereby improving the detection accuracy of the scraper;

[0045] After cleaning, the ink scraper rises, and the pressing block 23 moves away from the support rod 22. After the support rod 22 is no longer squeezed, the sealing door 21 closes the cleaning tank 2 through the spring reset, driving the support rod 22 to return from the horizontal state to the inclined state, and the air outlet 26 blows air to the ink scraper to speed up the drying of the ink scraper, shorten the preparation time of the ink scraper, and improve the detection efficiency; then, the rotating drum 12 drives the correction plate 14 to rotate to the bottom of the ink scraper, and the electric telescopic rod 16 drives the blade of the ink scraper to rest on the correction plate 14 through the knife holder 15. The light source of the lamp 17 passes through the gap between the correction plate 14 and the contact part of the ink scraper, and forms a pattern on the imaging component 18 according to the principle of pinhole imaging; and the imaged pattern will be formed according to the formed pattern. The distance between the imaging component 18 and the scraper is enlarged, which makes it easier to highlight the uneven parts of the scraper blade, so that the detection device 1 can more easily detect the flatness of the scraper, thereby improving the detection accuracy and further improving the effect of real-time monitoring; moreover, by forming an enlarged gap pattern on the imaging component 18, the detection device 1 can more easily analyze the imaging pattern and calculate the parameters required to adjust the flatness of the scraper through the uneven difference on the imaging pattern, such as the height difference between the convex part and the concave part on the pattern, so as to provide data for the staff to trim and maintain the scraper, speed up the trimming work of the scraper, and further improve the efficiency of real-time monitoring of the scraper;

[0046] When the scraper blade is inspected optically, the circulating air pump 25 is turned off to prevent the air flow from affecting the inspection work; the staff can change the inspection method at any time according to the different inspection requirements of different scrapers; if a quick inspection of the scraper blade is required, the quick inspection of the scraper blade can be completed by the above-mentioned flatness inspection method; if a more detailed inspection of the scraper blade is required, the staff can perform a more detailed inspection of the scraper blade through the inspection instrument 11, so that the inspection device 1 can adapt to the inspection requirements of different scrapers, thereby improving the convenience of use;

[0047] Furthermore, after the scraper blade detection is completed, the motor 13 drives the rotating drum 12 to reverse and reset, and then quickly switches between forward and reverse rotation, shaking the cleaning solution to surge in the cleaning tank 2, thereby achieving the purpose of scrubbing the cleaning tank 2, improving the cleanliness of the cleaning tank 2, avoiding residual ink and contaminating the subsequent scraper blade, thereby improving the cleanliness of the scraper blade and further improving the detection accuracy.

[0048] Embodiment 2:

[0049] On the basis of the first embodiment, a reel 3 is connected to one end of the sealing door 21 which is close to each other through a spring sliding connection, and a reel 31 is evenly arranged inside the reel 3 and a sticker 32 is rolled up, and the outer surface of the sticker 32 is coated with a light-absorbing paint, and the correction plate 14 is coated with the light-absorbing paint; a second bag 53 is provided between the sealing door 21 and the reel 3, and the second bag 53 contains an air nozzle for breathing outward; the light-absorbing paint is a conventional paint used to reduce light reflection, so as to prevent the light emitted by the lamp 17 from being reflected on the scraper and the correction plate 14, thereby affecting the detection work;

[0050] The sealing door 21 is slidably connected with a pressing column 34 through a spring, and the pressing column 34 is meshed with the surface of the winding shaft 31. The pressing column 34 is located between the sticker 32 and the winding plate 3. A sealing strip 35 is provided at the end of the sealing door 21 close to each other; a slide plate 36 is slidably connected to the top of the winding plate 3 through a spring, and a pressing shaft 37 is rotatably connected to the end of the slide plate 36; a middle seam 38 is evenly arranged on the sticker 32, and the middle seam 38 is an easy-tear seam composed of multiple small holes on a conventional roll of paper that is easy to tear open;

[0051] Specific working process: when the sealing door 21 is stationary, the two winding plates 3 are in contact with each other, the two winding shafts 31 and the sticker 32 are close to each other, and the winding plate 3 is in a state of being retracted into the sealing door 21, so that the No. 1 capsule 33 is squeezed by the reaction force generated by the winding plate 3 and is in a state of waiting for air to be sucked; when the sealing door 21 is retracted into the rotating drum 12, the sealing door 21 drives the No. 1 capsule 33 and the winding plate 3 to move away from each other, and the ink scraper passes between the two sealing doors 21 and enters the cleaning tank 2; after the ink scraper enters the cleaning tank 2, the No. 1 capsule 33 inhales air outward through the built-in air nozzle, so that the winding plate 3 drives the sticker 32 to be sucked outward through the winding shaft 31. The paper 32 extends out of the sealing door 21 and is closely attached to the upper part of the ink scraper. Since the ink scraper scrapes ink with its blade, there is no or residual ink on the upper part of the ink scraper, which does not affect the sticker 32 being attached to the ink scraper. The sticker 32 with light-absorbing paint is attached to the side of the ink scraper facing the lamp 17, and cooperates with the correction plate 14 coated with light-absorbing paint to reduce the reflection effect of the light emitted by the lamp 17 on the ink scraper and the correction plate 14, thereby improving the quality of the imaging pattern, so that the detection device 1 can more accurately analyze and detect the flatness of the ink scraper, improve the detection accuracy, and further improve the real-time monitoring effect of the ink scraper.

[0052] During the lifting and cleaning process of the ink scraper, the reel 31 squeezes one end of the sticker 32 against the upper half of the ink scraper. The ink scraper rises and falls, and the friction drives the reel 31 to rotate, rolling the sticker 32 attached to one side of the ink scraper, so that the ink scraper and the sticker 32 are more closely attached, avoiding the sticker 32 from falling off when it is lifted and pulled, thereby affecting the detection work, thereby improving the detection efficiency; after cleaning, the blade of the ink scraper rises away from the cleaning tank 2, and the lifting of the ink scraper pulls the sticker 32, driving the reel 31 to rotate and unwind, and stick the subsequent sticker 32 to one side of the ink scraper;

[0053] When the ink scraper is lowered, the reel plate 3 extends out of the sealing door 21, and the reel shaft 31 is away from the squeezing column 34. At the same time, the squeezing column 34 is not squeezed and the spring stretches to move it, that is, it slides on the inner wall of the sealing door 21. At this time, the reel shaft 31 and the squeezing column 34 are not engaged; when the ink scraper is raised, the pressure block 23 is away from the support rod 22, and the sealing door 21 gradually approaches each other, and the reel plate 3 is also gradually retracted into the sealing door 21; when the blade of the ink scraper rises and approaches the reel shaft 31, the squeezing column 34 and the reel shaft 31 are mutually engaged. The sticker 32 is engaged, the rotation of the reel 31 is stopped, and the sticker 32 is pulled and disconnected from the middle seam 38, so that the sticker 32 is adhered to the side of the scraper except the blade, which reduces the reflective area of ​​the scraper surface and prevents the sticker 32 from covering the blade of the scraper, thereby affecting the detection of the blade, thereby improving the detection accuracy; when the blade of the scraper is away from the sticker 32, the reel 31 drives the sticker 32 to squeeze each other until the sealing door 21 is retracted, and also drives the squeeze column 34 in the engaged state to reset;

[0054] When the scraper blade is lowered for cleaning, the winding plate 3 is affected by the slow suction of the No. 1 bag 33 and has not yet fully extended out of the sealing door 21, and the winding plate 3 and the components therein are away from the scraper blade; when the scraper blade carries the sticker 32 and rises through the slide plate 36, the winding plate 3 and the components therein are close to the scraper blade. At this time, the slide plate 36 is affected by the spring, driving the pressure shaft 37 to press against the sticker 32 on one side of the scraper blade, so that when the sticker 32 is pulled, the pressure shaft 37 can keep the sticker 32 that has been stuck to the scraper blade fixed, thereby preventing the sticker 32 on the scraper blade from being pulled. The sticker 32 is pressed against the scraper surface several times by the pressing shaft 37 in cooperation with the reel-up shaft 31, so that the two are more closely attached, and the stability of the sticker 32 is improved, thereby improving the detection efficiency; the sealing strip 35 is provided, so that when the sealing door 21 is pressed close to each other, the sealing strip 35 intervenes to improve the sealing degree of the sealing door 21 to the cleaning tank 2, thereby preventing the cleaning solution from leaking and contacting the sticker 32 during the cleaning tank 2, thereby affecting the quality of the sticker 32, thereby improving the convenience of use.

[0055] Embodiment three:

[0056] On the basis of the second embodiment, the bottom of one end of the winding plate 3 close to each other is connected to the wiper plate 4 through a spring sliding connection, and the end of the wiper plate 4 is provided with a water absorption block 41; the position of the wiper plate 4 close to the water absorption block 41 is hinged with a fan-shaped block 42 through a torsion spring, and one side of the fan-shaped block 42 contacts the bottom of the water absorption block 41; the fan-shaped block 42 is set to swing in one direction, and when the fan-shaped block 42 is stationary, it is tilted toward the bottom of the cleaning tank 2;

[0057] The surface of the sector block 42 is wrapped with rubber 43; the inner side of the sticker 32 is coated with water-absorbing material 44;

[0058] An air bag 45 is provided on the inner wall of the detection device 1, and the air bag 45 covers the lamp 17; the air inlet and the air outlet of the air bag 45 are respectively connected to the air inlet end and the air outlet end of the circulating air pump 25, and the air bag 45 is in a square tube shape and can be extended; the air bag 45 is a conventional air bag component, which has a folding function, that is, when air is supplied to the inside, it maintains a fixed shape and stretches, such as the bellows on the organ, and when air is sucked into the inside, it maintains a fixed shape and shrinks and recovers;

[0059] Specific working process: when the ink scraper descends and enters the cleaning tank 2, the fan-shaped block 42 contacts the ink scraper; when the ink scraper rises and moves away from the cleaning tank 2, the fan-shaped block 42 contacts both sides of the ink scraper, and the wiper plate 4 is affected by the spring to squeeze the fan-shaped block 42 to one side of the ink scraper, and the fan-shaped block 42 swings around the hinged part as the axis, so that one end of the fan-shaped block 42 is open away from the ink scraper, and the other end is close to the surface of the ink scraper, so as to achieve the effect of scraping and drying the ink scraper surface before pasting; after the cleaning solution on the surface of the ink scraper is scraped off, it contacts the water absorbing block 41, and the water absorbing block 41 removes the ink scraper by contact. The cleaning solution remaining on the surface of the blade is absorbed, the dryness of the scraper surface is improved, so that the sticker 32 can be better adhered to the scraper surface, thereby improving the detection effect; when the sealing door 21 is re-closed, the fan-shaped block 42 is affected by the torsion spring to swing back to the original position, and one side of the fan-shaped block 42 contacts and squeezes the water-absorbing block 41, squeezes out the water absorbed in the water-absorbing block 41, and keeps the water-absorbing block 41 in a squeezed state, so as to prevent the water-absorbing block 41 from absorbing the cleaning solution when not working, thereby improving the dryness of the scraper, thereby improving the adhesion between the sticker 32 and the scraper, and further improving the detection effect;

[0060] By setting the rubber 43, the fan-shaped block 42 can indirectly contact the surface of the ink scraper through the rubber 43, thereby avoiding damage to the surface of the ink scraper and affecting the detection work; because the sticker 32 is coated with a water-absorbing material 44, such as a polyvinyl alcohol material, which is still sticky after absorbing water, after the sticker 32 is pasted on the surface of the ink scraper, if there is water on the surface of the ink scraper, the water-absorbing material 44 on one side of the sticker 32 absorbs the water and increases the stickiness, thereby increasing the adhesion stability between the sticker 32 and the ink scraper, thereby improving the detection efficiency; and, in order to prevent the ink scraper from being away from one side of the lamp 17 and dripping water during the detection process, the sticker 32 can be adhered to both sides of the ink scraper, thereby reducing external influencing factors during the detection process and improving the detection effect;

[0061] When the scraper is against the correction plate 14 and is ready for detection, the circulating air pump 25 blows air into the wind bag 45 to expand it. The wind bag 45 extends toward the scraper in a square tube shape and expands until it contacts the tool holder 15 and covers the scraper in the wind bag 45, thereby reducing the influence of external light on the detection result and improving the detection accuracy. The inner surface of the wind bag 45 is also coated with light-absorbing paint to avoid the influence of light reflection.

[0064] An arc plate 56 is provided at the end of the telescopic plate 52, and the telescopic plate 52 is located in the middle of the bottom of the arc plate 56, and the cleaning cloth 55 is located at the top of the arc plate 56, and the arc plate 56 is a comb-tooth structure; a scraper 57 is hinged on the top of the arc plate 56 through a torsion spring, and the scraper 57 faces the blade when contacting the ink scraper; a cleaning belt 58 is connected to the bottom of the cleaning tank 2 in a uniform rotation, and the cleaning belt 58 contacts the lower half of the cleaning cloth 55 in an arc shape;

[0065] An extrusion plate 6 is provided on the inner wall of the cleaning tank 2, and the extrusion plate 6 is close to the top of the cleaning belt 58, and the cross section of the extrusion plate 6 is wavy; the top of the arc plate 56 is slidably connected to a rotating shaft 61 through a spring, and the scraper 57 is hinged on the rotating shaft 61 through a torsion spring, and one end of the rotating shaft 61 contacts the extrusion plate 6;

[0066] A first nozzle 62 and a second nozzle 63 are respectively provided near the top of the inner wall of the cleaning tank 2. The first nozzle 62 is tilted toward the ink scraper, and the second nozzle 63 is directed toward the contact portion between the cleaning cloth 55 and the cleaning belt 58. The first nozzle 62 and the second nozzle 63 are connected to the water outlet of the storage tank 24. The collection port 64 provided on the inner wall of the cleaning tank 2 is connected to the water extraction port of the storage tank 24.

[0067] Specific working process: when the ink scraper contacts the cleaning cloth 55, the motor 51 drives the telescopic plate 52 and the second bag 53 to rotate through the cleaning shaft 5, and the cleaning cloths 55 on the two cleaning shafts 5 both rotate toward the ink scraper, for example, the cleaning shaft 5 on the left rotates clockwise, and the cleaning shaft 5 on the right rotates counterclockwise. In this way, the cleaning cloth 55 is kept on wiping the ink scraper surface from top to bottom, and the ink on the ink scraper is wiped in a way of maintaining one direction from top to bottom, avoiding wiping from bottom to top or in a non-uniform direction, resulting in the ink being spread on the ink scraper surface through the softening of the cleaning solution during the wiping process, resulting in a larger ink contamination area, thereby improving the cleaning effect, thereby shortening the cleaning time, and improving the detection efficiency;

[0068] Moreover, the ink scraper is wiped with a cleaning cloth while soaking, which speeds up the ink removal efficiency, shortens the detection time, and improves the real-time monitoring effect of the ink scraper; after the telescopic plate 52 indirectly contacts the ink scraper through the cleaning cloth, it is squeezed and inserted into the cleaning shaft 5, squeezing the No. 2 capsule 53, squeezing the cleaning solution in the No. 2 capsule 53 and spraying it out through the water spray hole 54, so that the purpose of wiping the cleaning cloth 55 and spraying the cleaning solution at a close distance through the water spray hole 54 is achieved, so that the ink on the ink scraper is subjected to multiple cleaning methods of soaking, wiping and rinsing, thereby improving the cleaning effect, shortening the cleaning time, and thus improving the detection efficiency; moreover, during the cleaning process of the ink scraper, the electric telescopic rod 16 drives it to rise and fall, so that while the cleaning cloth 55 keeps the rotating wiping direction fixed, the ink scraper increases the washing effect by actively rising and falling, that is, the effect of rubbing clothes up and down by hand, further improving the cleaning effect;

[0069] By setting the arc plate 56, when the telescopic plate 52 is retracted into the cleaning shaft 5, the area of ​​the second capsule 53 is increased by the arc plate 56, the volume of the second capsule 53 that is compressed is increased, the water spraying amount of the water spraying hole 54 is increased, and the flushing effect is improved; when the telescopic plate 52 is retracted to drive the arc plate 56 to approach the cleaning shaft 5, the adjacent arc plates 56 are inserted into each other's comb tooth structure, so that the arc plate 56 can be close to the cleaning shaft 5, and the arc plate 56 can also support the cleaning cloth 55, increase the support of the cleaning cloth 55 during the wiping process, and avoid the cleaning cloth 55. The wiping force of the scraper is insufficient, resulting in a reduced wiping effect, causing ink lumps to remain, affecting the pasting and detection of the sticker 32, thereby improving the cleaning effect of the scraper;

[0070] By setting a scraper 57, and the hardness of the scraper 57 is lower than that of the scraper, such as plastic, the scraper 57 is prevented from damaging the scraper; the telescopic plate 52 drives the scraper 57 to rotate through the arc plate 56, and the scraper 57 contacts the surface of the scraper during the rotation. The scraper 57 is freely swung toward the cleaning cloth through the hinge, and can maintain a good scraping effect with the surface of the scraper, cooperate with flushing and wiping, and further improve the cleaning effect, shorten the cleaning time, and thus improve the detection efficiency; when the scraper 57 rotates to the bottom of the cleaning shaft 5, it contacts the cleaning belt 58, and the cleaning belt 58 squeezes the scraper 57 onto the cleaning cloth 55. The cleaning belt 58 wipes and cleans the scraper 57 and the cleaning cloth 55, thereby improving the cleanliness of the parts and reducing the risk of secondary contamination; because the cleaning belt 58 contacts the lower half of the cleaning cloth 55 in an arc shape, the contact area between the cleaning belt 58 and the cleaning cloth 55 is increased, and the cleaning time of the scraper 57 and the cleaning cloth 55 by the cleaning belt 58 is extended, thereby improving the cleanliness of the parts;

[0071] By setting the squeezing plate 6, when the arc plate 56 drives the scraper 57 to contact the cleaning belt 58 through the rotating shaft 61, one end of the rotating shaft 61 contacts the squeezing plate 6, and one end of the rotating shaft 61 moves along the wavy surface of the squeezing plate 6, in cooperation with the spring between the rotating shaft 61 and the arc plate 56, so that the rotating shaft 61 reciprocates left and right on the arc plate 56, so that the rotating shaft 61 drives the scraper 57 to reciprocate left and right between the cleaning belt 58 and the cleaning cloth 55, so that the cleaning belt 58 cleans the cleaning cloth 55, and the scraper 57 and the cleaning cloth 55 rub against each other to clean, thereby improving the cleaning effect, shortening the cleaning time, and thus improving the detection efficiency;

[0072] The storage tank 24 delivers cleaning solution to the No. 1 nozzle 62 and the No. 2 nozzle 63. The No. 1 nozzle 62 is tilted to point to the ink scraper to rinse the ink scraper before immersion, reduce the ink content in the cleaning solution in the cleaning tank 2, and avoid excessive ink content in the cleaning solution, which affects the cleaning of the ink scraper; the No. 2 nozzle 63 points to the contact part between the cleaning cloth 55 and the cleaning belt 58, so that after the telescopic plate 52 rotates away from the cleaning belt 58, it is reset by the spring, and the No. 2 capsule 53 also elastically recovers accordingly. The No. 2 capsule 53 absorbs the clean cleaning solution sprayed by the No. 2 nozzle 63 through the water spray hole 54 for close-range flushing when contacting the ink scraper, avoiding the No. 2 capsule 53 from sucking in unclean cleaning solution, which causes secondary contamination of the ink scraper, further improving the cleaning effect, shortening the cleaning time, and thus improving the detection efficiency; the storage tank 24 draws away the cleaning solution in the cleaning tank 2 through the collecting port 64 to achieve the purpose of circulating the cleaning solution in the cleaning tank 2, improve the purity of the cleaning solution, and thus improve the cleaning effect.
